Tarsnap, while optimal for essential, mainline data, it really needs a file-based QoS feature where it can use or migrate to/from cheaper options like RRS or Glacier.
If anyone could make it work it's Dr. Percival, but I wouldn't want to be the one trying to figure out how to avoid astronomical charges for hydrating and transferring data, or accidentally making too many calls.
Cheap as long as you never need to read the data!
Kind of a ransomeware Lite.
They call it “legit ransomware”
Come on don't be like that just look at the quality of indihome and telkomsel they surely have it under control ;)
